• Aluminum Alloy Casting: Technology and Future Prospects

As an important light metal material, aluminum alloy has been widely used in aerospace, automobile manufacturing, machinery manufacturing, construction and other fields because of its low density, high strength, good corrosion resistance, excellent electrical and thermal conductivity and other characteristics. As an important method of aluminum alloy processing, aluminum alloy casting has shown a strong momentum of development in recent years under the two-wheel drive of technological development and market demand.

• Basic knowledge of aluminum alloy casting

Aluminum alloy casting refers to the aluminum alloy after melting, through the casting process to make various shapes and specifications of the casting. According to different processing methods, aluminum alloys can be divided into deformed aluminum alloys and cast aluminum alloys. Deformation aluminum alloy is mainly used for processing into various profiles, while cast aluminum alloy is mainly used for direct casting into parts. Casting aluminum alloy according to the composition can be subdivided into aluminum silicon alloy, aluminum copper alloy, aluminum magnesium alloy, aluminum zinc alloy and so on.

The casting process involves multiple steps, including batching, melting, pouring, cooling and cleaning. Among them, melting is a key step, and it is necessary to strictly control the melting temperature and time to ensure the uniformity of the alloy composition and avoid defects such as pores and inclusions. In the pouring process, the selection and design of the casting mold is also very important, which directly affects the shape accuracy and surface quality of the casting.
